I’m new to the club and this is my first cry for help.
I have a continuing problem with oil in the expansion tank on my 1990 300TE (130k).
The car was laid up for more than a year and once back on the road the coolant became emulsified oil. The head was removed and indications were that a leak had developed behind No4 cylinder between high pressure oilway and water jacket. The head was checked with a straight edge and reassembled with new head gasket. Coolant flushed repeatedly and car back on road.
Soon after, problem back. Head off again, skimmed and reassembled with new gasket and head bolts. That was over a year ago and I’m still mopping oil from the expansion tank each week. Oil level does drop but only very slowly, not a problem.
All work carried out following genuine MB workshop manuals. Yes I have a set!
Has anyone out there had similar problems so that we can share our experiences?
Despite the problems the car is still my favourite and remains a pleasure to own and drive.
